Unlimited Money
You must have two controllers. PLug the first one into the first slot, then plug the second one in the THIRD slot, with the second controller keep pressing start, every time you press start i think you get 10 000 dollars. Then presss start on the other controller to check your money.

Unlimited Money[Fo Real]
Ok, first off you DON'T need two controllers for this cheat. All you need to do is switch the controller two the THIRD slot and press start. (your 'backpack' isn't going to pop up ok) Each time you press start, that's 10,000g you get.
Then, switch the controller back to the FIRST slot and press start, and there's your money.

Unlimited Items[The Real Deal]
Ok, let me start off by saying, you do NOT get 99 of EVERYTHING!Some things are like 78, some are 89...99 of everything is NOT right. And second, when they say everything, THEY MEAN EVERYTHING! Like tools...and seeds you didn't even know existed.
But just follow the same procedure as the 'Unlimited Money', but instead of clicking start, press the purple 'Z' button.
